• LED slart button

• Right and left flipper burton

• Slam switch on coin door

• Righl and left coin switch

• Nudge switch

Each push and each release will cause a "popping" sound


No sound for any switches means the volume control, the speaker, or its connections should be checked. If only one or a few switches produce no sound, then check the switch for problems.
